Bi foils with 9-40 µm thicknesses were obtained by a melt spinning method. The microstructure and resistivity in at cryothermal treatment have been studied. foil samples characterized using XRD to identify the plane orientations SEM observe morphology. of was measured two-point probe method temperatures 77-300 K laboratory cryostat. formation polycrystalline specific orientation allowed us disc...

Electrically conductive films are key components in most printed and flexible electronics applications. For the solution processing of conductive films, inks containing silver nanoparticles (AgNPs) remain important because of their relatively easy processing and generally low resistivity after a sintering procedure. Because the commonly used, moderate sintering temperatures of 150-300 °C are st...

Langgu Depression is a mature oil and gas exploration area with complicated lithological physical properties. The varying formation fluid, low-resistivity hydrocarbon-bearing reservoirs, non-uniform logging series greatly increase the difficulty of reservoir identification. Monte Carlo method employed to simulate neutron–gamma responses saturation influential factors. According result, new iden...

mrs method is one of the new geophysical methods that directly detects the groundwater. by using this method, one can determines some parameters of aquifer (porosity, permeability and transmissivity). the purpose of this research is the application of mrs method in the conductive ground. combination of mrs and rs method is used for better detection of the aquifer in the region of abyek located ...

one of the main factors of premature deterioration of concrete structures is the corrosion of reinforcements. chloride penetration of concrete is one of the main reasons of this phenomenon. therefore, to have durable structure, it is necessary to have concretes with low permeability.there are various methods to evaluate permeability of concrete. finding a relationship between them can be useful...

Recently, there has been interest in semimetallic rare earth monopnictide nanoparticles epitaxially embedded in III-V semiconductors due to the drastic changes brought about in these materials’ electrical and thermal properties. The properties of terbium codeposited with gallium arsenide by molecular beam epitaxy are discussed here. These new materials were characterized by x-ray diffraction, R...

We study a trial wavefunction for an interstitial in a Wigner crystal. We find that the electron correlations, ignored in a conventional Hartree-Fock treatment, dramatically lower the interstitial energy, especially at fillings close to an incompressible liquid state. The correlation between the interstitial electron and the lattice electrons at ν < 1/m is introduced by constructing a trial wav...

It is shown that formation of clusters of charged impurities on graphene can suppress their contribution to the resistivity by a factor of the order of the number of impurities per cluster. The dependence of conductivity on carrier concentration remains linear. In the regime where the cluster size is large in comparison to the Fermi wavelength, the scattering cross section shows sharp resonance...
